[comp.unix.xenix] SCO Xenix and _Z1000ups* functions

tts@ttank.ttank.com (Karl Bunch) (06/27/90)

Any ideas as to what the SCO Xenix 2.3.2 kernel functions _Z1000upshalt
and _Z1000upspoll are for? I could guess but, what is a Z1000?

And, is it possible to fake the Z1000 interface to allow other smart UPS's
to take advantage of any stuff that is already coded into the kernel?

A Z1000 is a multiprocessor Unix box.  The one I've got is running
Xenix, but since SCO is now shipping Corollary's MPE (Multi Processing
Extensions), you can now run SCO Unix on it.

You forgot _Z1000upstart.  I would guess that they're for controlling
the built-in UPS.  Unplug the sucker from the wall and you get no
reaction, other than that it runs /etc/powerfail, which tries to kick
everybody off and shut the machine down.

My biggest complaint with /etc/powerfail is that it never checks to see
if it got AC power back.  Perhaps a little hacking with the above
functions will let me fix that, eh?

I've heard rumors that Zenith was the first to use Corollary's technology,
which is believable.  Unfortunately, they're fairly close-mouthed about
the product.  That's too bad, because it's one heck of a lot of machine.
The one I've got has four processors, 32 MB of memory and 600 Meg of disk.
That's really not enough disk, but Zenith donated it to us, disk and all.
Beggars can't be choosers.
